Could they fear with SW, LN, MimbleWimble, .... (see e.g. BS Roadmap) these tasks cannot be ensured ?
1) SW does nothing to jeopardize their plans, whatever they may be.
2) The same goes for LN.
3) MimbleWimble might have an effect, but they can't prevent that one.
also Chinese miners (in collusion) might not risk to let bitcoin be changed to be more anonymous?
Now this may be an interesting assertion. That may result in miners getting 'fired'.
