Well, except the mods, he doesn't pay them.

Or the people who made moderator tooling to hack around his lack of moderator tooling.

Or those who wrote entire third party apps to get around his lack of viable third party apps.

Or those people who had to implement accessibility for the blind or otherwise disabled to get around his lack of tooling for the blind or otherwise disabled.

But besides all those people, yeah he pays the bills.

Well okay he doesn't actually pay anything, it's the investors and advertisers that pay the actual bills.

But other than all that spez contributes by.... Uhh ..... Lowering server costs by causing a mass exodus?

That would be its investors.

Rent a storefront

Get people to run and supply it for free

Sell the supplies and profit

Build a platform

Recruit free labor

Replace them when they stop working

Adding thousands of employees and pissing away profitability to force these kinds of no-win choices ain't exactly "payin' da bills."
