The offer had no limits (someone who was at the company for 2 days took it). Matt was also willing to continue sponsoring visa for the 6 months for whoever is on an work visa.
This was a very distracting 4 days, I'm glad it ended quickly, the dust is settling now, and we're slowly going back to work.
The whole drama is not done, but the colleagues and friends leaving all at once is done, and that was stressful, you don't know who's leaving next until you see their name.
To OP's point, I don't think the provided buyout window was long enough to determine that. If a bunch of other shoes drop, like more stuff comes out of discovery with the WP Engine lawsuit, knowing that you only had 4 days to accept or GTFO might still leave a bunch of on the fence employees.
