Is that what's going on? if yes, are big-tech service-api's so popular that indie web-backend engineers use them all over the place? My impression was that most of the backend stuff you do is on the webserver, and part of the work is to survey github open-source projects and install the ones you like (and the ones that are popular) on your webserver.
Wasn't the community shift from php to node.js/npm (or ruby, or python, take your pick) touted as some kind of a mini-revolution, something that'll make your life easier as a backend-dev? Turns out you guys still prefer someone else (in this case, 4-eyes big-tech) does the serious work for you?
I'm really not sure I understand the landscape.
