I used the service and as a techie knew it wasn't really sustainable but the average consumer buying in good faith wasn't warned that their purchase might be so short lived. Might have been hidden in the TOS but that won't cut the mustard in many jurisdictions and will be an expensive battle.
I suspect they made a small amount of sales and it'll be cheaper and easier for them to credit than fight.
I'm not saying Google won't pay out, but I just think there's a lot of reasons why they might not.
Might sound crazy but the 100m would be more effective to the brand than spending 100m on marketing.
Further, Google exited this market. Do they really care about marketing to these people anymore? Their main revenue is non-consensual tracking, it's not like being mad at Google is going to matter unless you really go out of your way because of it.
