Yeah, I've been following this on Reddit and elsewhere.
Apparently, the T1s were being made at the same factory as the fake Zealio/Tealio switches.
Some people also claimed evidence that the T1s were using unlicensed Zealio components. (Not sure if V1 or V2). There may have been unlicensed Gateron components in the T1s.
I was paying close attention to this because I had an unfulfilled order for a testing quantity of Stealios and T1s at the time this all erupted.
I had to cancel the order, because if those switches are pulled from production, then a testing quantity of them is not useful to me - I was trying to see which KBDFans switches to use for a board.
(Although it might have been better to go ahead with the order. T1s and even the fake Zealios (Stealios) have become a novelty item overnight. Who knows, the T1s might to go $3/switch.)
Regardless of whether the T1s contained unlicensed parts or not, it is said that Wei at KBDFans pulled the T1s out of production as a goodwill gesture to Zeal.
If I were KBDFans, I would be busy setting up the new factory to produce the successor to T1s. There's clearly massive demand for a medium-weight tactile for $0.55.
