Netflix and Spotify also auto bump the prices even for auto-renewal. I believe the issue here is that Microsoft created a new pricing category while keeping the $99 one, but bumped everyone to the new one. That is where it gets sketchy.
If they eliminated the $99 one then it might be a nothingburger.
Might be class action worthy.
To me this is what seems odd, how can you charge my card more without me explicitly allowing that?
I would have thought visa and Mastercard would have something to say about it, but they’re probably in bed with FAANG anyway.
