100%, although I think it was the other way around. GOP treated the Tea Party as a legitimate movement with ideas worth hearing/catering to. Before long, those same members found themselves either falling in line or challenged from the right in primaries. That group morphed into MAGA, which again was absorbed by the GOP as their new identity.
Occupy faced overwhelming media bias against it. A good chunk of major cities passed anti-protest laws that curbed it.
The Tea Party was an astroturfed “movement” funded by the Koch brothers that resulted in officials being elected. The overall goal was to bring the US further right and that was accomplished so they stopped funding it.
Occupy was smothered from within via the use of ops, change my mind. It was one of the very few popular movements that got really close to the true crux of the issues in society, and right after it failed we got inundated with extremist identity politics tearing a potential class struggle apart.
Occupy fizzled due to it's own structure. It was a truly grassroots movement, not centered around any single leader or leadership structure. This ended up being the biggest issue that caused the movement to end. With no central structure, there was no central message. The media had no one specific to talk to, so they were free to talk to whomever they wanted, regardless of how well that person was able to articulate the message. With no well articulated message, people who weren't already playing close attention had no idea what the occupy movement was about, and they ignored it in droves.
Occupy didn't really have defined goals. It had a loose coalition of people who were upset about similar things but didn't really agree on what needed to be done to fix it.
The Tea Party was the prototype of what the GOP would become. The party believed that they could control the radicals for their own purposes. They should have stomped them down. Instead they ended up in a hostile takeover situation. Now the GOP politicians are terrified of being deselected in their own electorates so they must engage in theatrical MAGA performances.
The Tea Party never went away, they evolved like a successful virus.
