@arnoldboer I love the ambition, but I think you're going to find that "IT users" is just too large of a class to actually activate en masse. Especially since the "uninformed masses" are a large majority of the users of the big tech in question, and real alternatives are hard to come by.
I'd start a little smaller - think about how you can make a better alternative to one of those pieces of big tech, get together some folks to make it happen, and drive change one piece at a time.
