Do we know if it blocks you from downloading "game key" cards? In that case you're effectively stuck with Switch 1 titles. Not that you should need a "workaround" for being punished because someone else did something.
While not technically bricking, the restrictions are very heavy, especially considering that you can run into the situation innocently. Buying something with the possibility of this is a risk, and OP is very understandable for not liking this risk.
The Steamdeck is more expensive than buying two Nintento Switch 2s? Theres definitely a dock for the Steamdeck, and you get all your Steam games OOTB, in my case thats hundreds more games than any Switch.
I don't like this practice, and it's one of the primary reasons I'm not buying a Switch 2, but his console wasn't bricked, it was just banned from playing online. And don't trot out that tired old "effectively bricked" line, words have meanings, and the words you said do not mean what happened.
If someone bought it for online play specifically, then there is no difference between being banned from playing online and the console not turning on. You're just nitpicking on the meaning, but we know what happened.
