It’s really hard to generalize about leftist groups. The communists that feel this way have formed co-ops, or are cooperating with anarchists to do something like syndicalism (focused on unionizing existing businesses).

But the methods to start and grow businesses in a capitalist country inherently rely on acting like a capitalist. Getting loans requires a business plan that makes profit, acquiring facilities and other businesses requires capital. Local co-ops exist because they can attract members and customers that value their co-opness, but it’s very hard to scale that up to compete at a regional level. It’s not impossible, but it’s hard to view it as an engine for vast change.

Communists that focus on voting are delusional (in my opinion) but like all reformists they view the existing government as the mechanism to make widespread change.

That salary number is all ~700 employees, not just “executives”. That averages to about 150k apiece, not unreasonable for what is probably mostly tech workers.
