p.s. yeah, i use amazon web services. i run software services in health care and that's the only government-approved option i have, aside from microsoft azure. and yes, i use youtube. not to mention other awful things. the problem is that these monopolies often leave us with no choice. i would rather have alternatives, but that can only be achieved collectively and i'm glad to participate in that struggle. if warren or sanders get elected, we may see some big things on the big tech front, though i suspect the senate will have to be won, as well, at some point during their presidency.
with corporate stuff like food and clothing, where i can make extreme ethical choices on my own and still live relatively normally, i do that. for example, unless i am in a socially situation where it would be rude, i NEVER ever frequent a fast food restaurant or a coffee shop like starbucks. i rarely buy anything online and am glad to pay more at a local shop. i also don't own a car and only use one (as driver or passenger) a handful of times a year. almost everything is by bike or on foot, with public transportation as fallback in situations of extreme weather.
