A lot of people tried to sound the alarm. It's not "the cloud", it's "other people's computers". And given that other people own these machines, their interests - whether commercial or ideological - will always come first.

Plus the machines they don't technically own--like Microsoft's attempts to force online accounts, bloatware, telemetry, etc.

To be fair, most people understand that risk. It’s just it is very convenient in a lot of scenarios and some businesses might have not even started without it. Privacy is not that big of a concern for a big chunk of people. And they’re basically voting with their wallets.
