We appear to be pretty far from the "100%" confidence level you originally provided.

Second, even if they did have a lease, statutory notice and penalties are nowhere nearly as strict as they are for residential lockouts (where statutory civil punitive damages untethered to actual damage do in fact apply).
In any case, if they want to claim damages, they're going to have to (a) document actual damages from WeWork's action and then (b) take it to court and wait a year or two to have a chance at recovering, in what will, due to their own actions, be a complicated case.
Nothing is going to happen here. Everyone is simply going to move on.
But, as I showed above, even commercial licensors have protections too...with notice needed and treble damages applying. Punitive damages could apply as well. In the end though, kicking some people with laptops (probably) out of their offices would, I would guess, result in a 5-figure award if it went to court...which would make it a somewhat marginal case (even if they were awarded legal costs as well).
Small claims court would probably be a guaranteed $5,000 though.
Does WeWork care about a few thousand dollars vs. stanching the flow of someone spreading bad PR about them? Probably not.
OTOH, now people know WeWork management have no compunction in telling you to GTFO ASAP (legal or not), and for the more risk averse larger tenants, that might be quite a concern...particularly given how much more WeWork charges per square foot (2x++), compared to just an ordinary 1 year sublet in the same area.
So in the end, I would still not do what they did. I would have a) Sent them a legal nastygram b) booted them off the internal network c) given them 10 days notice
but I'm the law abiding type :-)
I was wrong about NYCAC § 26-521 - 529, that's only for dwellings.

Note WeWork usually gives you a designated, numbered, suite, which might confirm that it's a lease. In the above-- "One last “don’t” for a licensor looking to remain one in the eyes of the law: don’t designate a particular space for licensee’s exclusive use. "
