Haha, normally I'd agree. And, I think that's one of the reasons no big company put any real effort (that I'm aware of / can think of at the moment) into trying to create and deploy a twitter-like service.
The "Musko-cringian" empire is an unbelievably ridiculous gift, here. Some of the timing couldn't be better.
Now, even with that backdrop, it's quite likely "Threads" (ugh, ... marketroids) won't take off like wildfire. But, I think we're at something of a fork here. Either this will be the competition current incarnation Twitter needs to start turning things around, or Threads will capitalize on each future misstep, service outage / problem, etc.
Threads has a sort of balanced position, in terms of marketing / uptake. Absolutely not the multi-faceted "cachet" of Bluesky Social, rather, the opposite ... arguably even "less cool" than Twitter (was) ... But, it also has the low friction user sign on you mention, part of an ecosystem incredibly widely used (a winning formula in America, especially, is convenience - about the best marketing available, itself), plenty of technical heft behind it, etc.
It could easily displace Twitter, and I think more quickly than many might argue.
