If you are going to quote half the article (that I've just read) to make your point, I'm definitely not going to make it to the end of your comment.

I don't need to read it again, thank you.

TL;DR:

They're using the wrong denominator, comparing apples-to-oranges. They aren't actually revealing that an exodus didn't occur, they aren't debating any numbers or adding any new data.

I added context for people who aren't familiar with the UK non-dom status, or the original intention of the legislation.

They're also a very biased organization, same as the organization behind the original report apparently.
