The article has one false assumption, "that IDERA is a company that focuses on SQL & other IT performance tools". It's not. They started focusing on developer tools in 2015, acquiring Embarcadero (Delphi and C++Builder.)
Disclosure: I work there. So I know that they are more than the article says ;)
I personally would suggest waiting and seeing what happens. Usually when there is an acquisition it is a good opportunity to correct mistakes the previous owner made. I'd suggest the author of this article actually contact Idera, let them know his thoughts, rather than posting a blog only. There are real people at the company and they'll read feedback, and now is a good time.
