Economically they are rent seeking. You pay a subscription to them for further access to their brand. They also fill the market niche created by alienation, serving a social and economic function here. They qualify as petit bourgeoisie I think.
They are absolutely petty bourg and many hire writers, editors, videographers, marketers, managers in either semi-prole waged positions or as inter-bourg contract services. Many are outright capitalist to Imperialist when enlisting proletarian, colonized, or neo-Colonial labor to produce their merchandising.
None of them are proletarian (unless they primarily support themselves with wage labor for a capitalist).
I think a lot of them are just in a position to have the imaginary class position of being petit boug in the same way a guy with a retirement package and a mortgage has the option of convincing himself the stock market and real estate's ability to Maintain Value are the most important things in the world.
