I know you meant this as a joke, but I want to emphasize a general point - one of the things that totally dumb down conversations about economy is people grouping ideas under labels like "communist" or "libertarian" or whatever and evaluating them in batches.
If done in good faith, I think it's legitimate to start with approximate labels, like "libertarian", and the arguing parties can then proceed to make their position clearer if necessary. Hopefully, this saves time.
Also, I think it's fair to describe someone that believes in the importance of "workers should own the means of production" as a marxist (at least it's more accurate than socialist or communist).
The founders, directors and investors could still own 51% of the company.
Heck, if they wanted they could offer only the bonus payout incentive structure with no equity or revenue share. In essence that would still encourage employees to automate the company. Employees work themselves out of a job, and the owners reap all of the automated revenues.
Or you could not be a dick.
