UASF is just any random node throwing a comment into the useragent but still waiting for weeks after 'activation' to actually get an implementation that does anything more than the tier network.

where as using the implementations that have dynamics actually start allowing blocks over1mb to be built without needing to be spoonfed yet another release download.
where everyone thats part of the network are all on the same level playing field of a peer network, not tier network

(understand the difference between peer and tier)
 learn the consequences of the tier network, the dilution of full nodes that are not equally syncable to each other, where the downstream cesspit of prunned, stripped, nodes that cant sync and become RELIANT on upstream nodes.
think about it (using the bitcoin network hat, not the blockstream defender hat)

peer networks is where people dont need to move funds to new keypairs and everyone can benefit from real extra space even using native keys and everyone is equal full node.
