Fair points, but maybe stick around anyway.
I'm here for similar reasons, but mainly because the other site became extremely cumbersome for me to use. It no longer fit with the way I "consume" information and entertainment, which is largely on mobile devices. Post sale, the standalone app and tapatalk interface crash constantly, and the website is miserable to use, even on a laptop or desktop. Granted, I'm not using an ad blocker, but it is what it is.
I have friends on both boards, and enjoy the defender community as a whole. I admire what Dave and Chris set out to do, and it fit with my wants as well. That said, had the sale of the other site been seamless from a user perspective, I may not have invested as heavily in participating here.
At the end of the day, I'd like to see this forum succeed, and I believe that for that to happen, content is king. For me personally, it doesn't all have to be technical excellence, particularly if there is to be a true community feel. Moderators are necessary, and I think Dave summed it up nicely.
So, that's a long winded way of saying stick around. A forum needs its members.
Heck, RBB has a three page thread on how to get four bolts in. That's stinkin awesome.
