I'd give this at least even odds.

Based on some ancient personal experience you can also bet that the EULA will be rewritten to forbid people to use Windows 11 to develop this sort of workaround. Which is to say, if this is not a violation of the license today, it will be soon enough.

I'd bet to 2:1 that it won't happen. Few people will bother, and the people that do get this tool are the type of people that that cause disproportionate issues if you anger them.

Most people are so bombarded with ads on the web that they scarcely think it weird that their OS does the same, anyone who cares about this has been able to do something about it a long time ago, I have never seen an ad on my windows 10 installation.
