Some of them are chuddy merch grifts specifically intended for fundraising. Now, you could argue that printing shirts and stickers and posters and flags in a co-op is something leftists have done forver, and you'd be right about that, but when you start a store for thin blue line merch or an agitprop site selling reprints of public domain theory or a food supplement grift or whatever these bozos are doing, it makes a difference when you have the funding to start out with several full-time employees, can afford advertising to make yourself known, can data mine information on potential donors and get additional funds if it takes longer to get everything going. It's much easier to scale this kind of stuff up when you go in with more capital than a used screen printer.
