@prologic@twtxt.net At least when it comes to personal use, it also depends on how much data you’re storing, how important it is and how much you’re fine with using dirty tactics.
For a lot of people the free options are enough, or the combination of them, at least. Neither is there anything, preventing you, from using alts on those services (other than the impracticality, of having everything on a different account).
For data you want to share, but don’t mind loosing, there’s also sites, that let you forcefully connect your account to some companys paid Google storage, that you can then use, until they find and kick you, or cancel their subscription - but they can never get your OG Google account banned for doing this.
Lastly there’s also Chinese companies, that let you save upto 1 or 2 TB, in return for most likely mining that data, having it linked to some adware and wanting money for faster download speeds. These services can also be exploited to get those paid speeds and features for free and the ability to use it without the adware, making it usable, if you don’t care if the data is private.
So you can have all the cloud you want, for free. What you pay for is privacy (or the illusion of it), convenience and the peace in mind, that you’re not a “cloud pirate”.
