Some would argue that there are at least two parts to the movement, of which one is focused on actual work reform and can be contrasted with a faction of true "lying flat" slackers.

There are two possible ways I’d frame that, personally:

1. There are two separate movements. I’d argue that people who want reform are not remotely related to people who don’t want to work.

2. Every movement will always have extreme factions that don’t necessarily align with the primary goals of the majority.

We saw plenty of #2 with Recent social movements.

That’s absolutely what it is. The original antiwork user base was people who literally do not want to work at all even if it was reformed to be fair.
