Or... They were so pissed with Chase due to this nightmare they had to go through, they looked for alternatives, found something, so they mentioned it in the post.

Disregarding is fine as you don't know if they are honest, at the same time I wouldn't attribute evil intentions either.

It's like when a native iOS developer says the best apps are truly native. It could be that they tell you that so that you hire them and their niche stays strong... or they really believe it and that's why they are iOS developers.
