I’ve never taken apart a Topre board, but looking at this video video, I’d say it was doable. Fiddly, maybe, but then again, so is opening up every switch on an MX board, too. Take your time, be gentle, pay close attention to what you’re doing… You’re probably going to be fine.

Before opening up or resoldering any switches, I’d short the two pins with something (tweasers or similar) to confirm or rule out the switch itself as the cause.

They don’t, officially, as far as I know it’s always been an “at your own risk, might get your account banned” endeavor.

No, problem not solved, problem half-heartedly worked around. People dislike Discord for several reasons, bridging it to whatever different platform will at best be a bandaid.
