They’re missing the damned point. I have never used Facebook, but on any service if I’m paying a monthly fee it is to remove myself from the ad-based enshitification.
It’s also what drives me crazy with respect to Microsoft products. I pay for MS 365, and I’d even be willing to pay for Windows if they’d leave me the fuck alone. I pay for ProtonMail and they do leave me alone, so I’ll always stick with them. Any app that I use for which I can pay to remove ads, I do it… unless it’s a subscription and I can’t quite justify the perpetual expense, like for my preferred weather app MyRadar.
Hell, I almost bought into the MyRadar investment pitch until I saw that giving them $400 still wouldn’t net me a lifetime subscription.
