It devalues the products of people that aren't bullshitting you. Say with fake-unlimited the "real limit" is 4TB before they start terminating you, but a different provider provides 5TB of capacity.
Because the former is allowed to outright lie, there is no way for the latter to effectively communicate that they are in fact offering a better product, instead they too have to make a bullshit "fake unlimited" claim to compete. Now because nobody has to actually back their claims with anything, they are infact massively incentivised to cut the "real storage" limits, because it will cut their costs, and they can still keep making the same claims.
Its a market for lemons[1] race to the bottom, and everyone loses, producer and consumer because scamming liars cannot be reliably assessed beforehand. So consumers lose faith in the entire market segment, and providers offering actual legitimate services become unsustainable.
Here's what a sane person would do: retain the 10GB. Disallow any further upload while usage is above 100% (Dropbox doed this).
No, this isn't what Microsoft is doing. I used to think one drive was unaffected by all the bs surrounding one drive for business but no. This is a dysfunctional company.
Now that I think about it, it gives me pause about why I should even consider Microsoft technology like dot net core. They'll find some way to screw you over even if it doesn't benefit them to do so.
Edit: sane
Ubuntu is a fine OS.
Oh and I've given up on anything named one drive forever. The time am can't be trusted with anything worth anything.
The former: if everyone just played along and used things reasonably we would still be benefiting from cheap storage.
The latter: stop playing games, "unlimited" is an unacceptable lie and we will push you into admitting it.
