Your welcome to stay but personal attacks against the site owner will not be tolerated. Also, derailing an otherwise positive thread is not very constructive.
I haven't personally attacked anyone, I made a generalized comment voicing my concern that most of the very knowledgeable members have left the forum.
Quite how that is considered to be a "personal attack against the site owner" is a mystery to me, I don't even know who the site owner is.
If I were him/her I would be very concerned that the once popular site I own is hemorrhaging its knowledgeable members. Once they have all gone what will be left?

Edit: Most importantly I'd ask myself why they have left and what can I do to prevent the few remaining knowledgeable members from leaving.
I'd also listen very carefully when they point out the problems with the forums.
