Engineers who find it distasteful should be happy to know engineers typically get way more equity than sales reps.

That isn't true. Early sales employees ('customer success', 'technical sales', 'growth', maybe product roles) get just as much equity as engineers who join at a similar time. The difference is that engineers often join earlier, with the commensurate risk that comes with.

Also equity rarely pays out so you'd need to be comparing the probability of an exit that actually rewards the share class that engineers get, whether or not they've been diluted to nothing, whether there's a secondary market to sell on before an exit event, etc. It also depends on whether someone even wants the potential reward equity gives them over the more tangible rewards of money and perks.

Comparing this stuff is hard.

The point here though, is that the company is rewarding sales people at a time when the product is doing poorly, which implies the leadership team care more about selling a bad product than turning it into a good product. I hope that's not the case because it used to be a good platform.
