Seeing various questions come up, hopefully this is helpful. Thanks to those who also helped with answers in prior posts.
TEA Q & A
Q: Were recent events intended or accelerated to justify moving?
A: No. If that was "the plan," I wasn't ready for it. Choosing and setting up the right forum for a community is a non-trivial, time-consuming endeavor.
Q: Why did you make a backup of the TEA thread?
A: This began after the data center fire. It scared us a lot. So, after everything was back to normal, I started making periodic, incremental backups of our content in the thread. Timestamps were tracked to avoid fetching the same thing multiple times. It was a slow crawl with a 2-second delay between GET requests. Given the number of requests a single page requires for all its elements, it moves along at a snail's pace, but the goal is not to negatively impact the forum. Now that TEA has moved, there's no need to back it up anymore.
Q: Are you going to duplicate the thread elsewhere?
A: Not as long as it exists here. It's bad for SEO to publish duplicate content. We built the thread here, so there's no need to have it elsewhere. We can always link to posts within it.
Q: I heard some people want to delete their content. Is that true?
A: No. During a time of high stress, some people blow off a lot of steam. Take what you hear with a grain of salt. We invested an inordinate amount of time and energy to build the thread. We're not going to destroy our own creation. As others have attested, there's a lot of good stuff in there.
Q: Why do you have domains for TEA?
A: This was also related to the fire. By having the domains, if something catastrophic happened, it'd be easy to point to a new location so folks wouldn't be left hanging. The domains originally pointed to the TEA thread here. Now they point to the TEA forum.
Q: Why did you choose groups.io?
A: It wasn't a vetted choice, unfortunately. Since there are already test equipment forums on groups.io, I figured I'd check it out in case the growing friction continued to be a problem. Then things went south in a hurry and a half-baked home was all I had to work with. Its UX has a lot to be desired, as we all found out afterward, but it's operational and has some useful bits.
Q: Why not just do A, B or C with the thread rather than move?
A: Because a single thread isn't the right solution. If you want to post about test equipment, it should go into the Test Equipment forum. If you want to post about a repair of test equipment, it should go into the Repair forum. If you want to chat about something else technical, it should go into the General Technical Chat forum. That's how EEVblog works. Putting your on-topic content at the bottom of a 130000-post thread is not beneficial to the poster nor the various forums here.
