That seems like an odd way to frame it, imo. "Holding the bag" usually implies something negative, as in someone will be "caught" with something bad. As in the employees are looking to dupe someone into buying what they are selling. But employees, outside of company officers, do not control what information investors get about what they are buying. They can't trick anyone into buying something, although they could theoretically benefit if someone else did trick buyers.
But it's a weird take, because employees are already the ones "holding the bag". Office space, cloud compute, etc. are all sold as COGS. VCs usually have some ability to sell their shares on the private market since they can negotiate to get their capital. Employees are often the only ones which are taking an IOU for their time and effort compared to what they could get elsewhere in the market. Employees are often the lowest class of shares which get paid out last and often reliant on the board to be able to sell on the private market. Yes, the employees decided to take this offer, on good faith, that their management would look after them. They are adults who made a, theoretically, informed decision. But structurally, they are set up to be the ones "holding the bag" if things were to go wrong with an exit.
So of course they want an exit. They literally have no other choice to get a return on their time/effort than for that to happen. (or some odd third thing like private dividends, but again, they have practically no control over that happening)
