Yes. As you said, same for YouTube TV. If you live outside of the ACC footprint as I do, you can still view these games on the ESPN app.
Luckily this only affects a limited number of games since most are on produced by ESPN and not RSN/Fox. Will be a huge problem for folks in the Southeast during baseball season though as the Braves games will not be on the streaming Live TV services. Same for any region with a Sinclair RSN. I imagine there will be immense pressure on the parties to figure it out when baseball season starts.
