WeWork is just saying they won’t pay expenses on meat. They’re not banning anyone from eating meat.

So they're just financially penalizing people that do

Nobody is telling WeWork employees they need to eat meat while traveling. Lots of places prohibit the expensing of alcohol.

Then why not just remove all reimbursements for food instead of penalizing just one group?

People have to eat. People don’t have to eat meat.

And company meetings and events?

You’ll have to note special dietary requirements beforehand, just like vegetarians have to do at most places today.
