Toxic positivity goes a step further. It's not just the gung ho "everything is awesome". There's also pushback against critique. In some communities, you can't say, "this project has aspects that are not good" without getting met with "be quiet, the devs are trying really hard".

I'm sorry, but certain things shouldn't involve participation trophies. Building bird houses with your kids in the backyard, yes. Building anything at least as complex as a toolshed for other people, no. At a certain point (i.e. when our work can have consequences for others), we have to take responsibility for our work, and expect responsibility from others.
