Personally I think that propaganda sounds like a basic day-to-day function of CoTech 
The idea of connecting clients to CoTech based on services sounds like marketing (I’m not saying this as a negative). I found this old thread from 2018 about marketing (bidding for projects as CoTech) and this stack of slides for marketing CoTech to clients, but I don’t know where those conversations went. I think that there was one project which some co-ops made a bid for as CoTech and otherwise haven’t done
In terms of advocating the starting and supporting of new co-ops, I think that there are quite a lot of organisations set up for this already? Likewise Coop Cloud looks really cool but I think it’s something CoTech could support, maybe fund, but not replace. Were you thinking of proposing/scoping a service for people to find coops that meet their needs more generally?
I suppose the element where CoTech and propaganda mostly intersect is in the CoTech newsletters, right? I had brought up a while back about extending the readership of the newsletters to a wider audience, but a lot of people preferred to keep it as internal to CoTech for now. Generally speaking I guess better than “marketing/advertising” of traditional companies we could look to other ways of producing content and maybe interactive content to spread co-operative ideas. Here’s a fun example: The Evolution of Trust
Loosely related, I like the IWW imagery. Using the Uber Eats and Deliveroo strikes as a context, I took this as an excuse to finish and publish a blog post that I’d started writing: Couriers Strikes, Unions and Co-Operatives. The post features @KingMob 's project Wobbly which is designed to help organise decentralised unions, and CoopCycle, which is a federation of courier co-ops mostly from Europe. The TLDR is that I’m suggesting that there’s crossover between class war, unionised workers and co-operatives, and finally that these kind of tools can be made into semantic web applications particularly for interoperability. I kept the post quite short (I might come back to it later), but I’m very interested in where we could go with that, what kind of things we could do, what kind of spaces we could create to help with it
