@Tealk - So sorry for the long reply, but you got me doing my research and I learned some things
Yeah, there should be regulatory bodies actively going after online businesses who make unproven statements or misleading claims.
However, are we really surprised? Hosting companies also advertise "unlimited" bandwidth & disk space, but in reality there is almost always a cap on this. There's always fine print about how fast data can be transferred, so if you take the Gbps/Mbps transfer speed for your hosting service and then multiply it by 60 (data per minute), then x60 again (data per hour), then x24 (data per day), then x30 (data per month) then you can see the TRUE maximum amount of bandwidth you can have, which is definitely not "unlimited". Sure, they say unlimited, but really it's however much data can be transferred with the max data transfer speed for the given month... and on top of that cap, there's a good chance you'll hit the CPU limits if people are actually uploading/downloading that much data to your server, meaning even the bandwidth cap is sometimes higher than the server can even support with its other hardware. The fine print always says something about how much CPU you can use, restricting your server use / traffic caps.
And then there's the whole misunderstandings of "unlimited disk space" because of the other fine print that most hosts have such as... You cannot offer a file uploading / storage service on shared hosting. You can't offer big downloads on some. Certain hosts prevent large videos from being stored on your site, or even large .zip files. Some hosts even put caps on the max file size. They make it extremely difficult to even fill up a server with files without breaking their rules. Simply put, you can't really use up 10-100GB (let alone "unlimited") without breaking some of the most common rules like not storing files for users to download, videos for them to stream, or allowing them to mass upload files. Avatars are usually fine (ex: for forums on shared hosting), but large forums have been forced to move off shared hosting because they need a faster server and/or they are breaking shared rules.
Hosting is designed to get you hooked on the "unlimited" word while almost never making it possible to achieve anywhere close to unlimited.
You will find it extremely difficult to find a host that offers unlimited space/bandwidth that would let you upload 1TB of files and do anywhere close to 1TB in bandwidth each month.
So, I know I kind of went off on a tangent here, but my point is that most hosting companies are already "lying" - even if they are legally okay because of the fine print. They find new ways to lie, such as saying "unmetered bandwidth", "unmetered disk space", because they know they can technically "not monitor" those statistics, but still keep their clients in line by monitoring the CPU and data transfer speeds that will directly make the unmetered space/bandwidth become capped at certain breakpoints. It's legal, but misleading!
The 100% green energy claims are extremely misleading, but there are a few other ways they can legally call themselves green while still using non green energy.
For example, a company can use non-green energy, but buy green certificates that go towards promoting green energy & technology to offset their emissions and pollution. This allows a company to hold a certificate saying they are a green company, but still not be fully green. This is pretty standard in hosting & other industries, even in 2019. You can also do trades where Company A basically doesn't use as much electricity as they could have... So instead of just not harming the environment, they can then sell/trade their "allowable bad electricity" to Company B who is at capacity... So Company B is allowed to use X amount of non-green electricity, but instead of finding a green alternative when they have reached their annual cap, they can trade with or buy from Company A who has the allowed non-green electricity available. This way the country as a whole is always (well, hopefully) operating at a level that environmental organizations have approved. Simply put.... If Company A is allowed to eat 20 apples, and Company B can eat 30 apples... If Company A only eats 10 apples, they have 10 left, so they can then give Company B their allowable apples, meaning Company A eats 10 still and company B eats 40, so the end result in the eye of government is that Company A/B combined ate 50 apples - So they don't care about the trading/selling of apples. This is also a frequent practice with green certificates / allowable bad electric.
