I didn't say it was a problem for most users ( aka passive users ). I said it's a problem because they make it difficult/impossible for tech/active/advanced users to switch it.

Yes. You just restated my comment. Not allowing tech/active/advanced users the option is the problem. I love comments that appear to debunked what instead you wrote but just write it in a different way and pretend it is new.
