May I suggest tweaking your mental model. Mike Johnson was THE MOST vocal opponent of mass surveillance, he was supposed to be the one to whip a republican congress to finally end Section 702.

Then he was made Speaker and literally overnight, flipped. In his words "I went to the SCIF and got the confidential briefing from sort of the other perspective on that, to understand the necessity of Section 702 of FISA and how important it is for national security. And it gave me a different perspective."

What his "briefing" was we can only guess. But there is a pattern on BOTH sides of the aisle they people are against mass surveillance, until they are put into positions of power and access to compartmentalized, classified info - and then they aren't. (for the record please dont interpret this as defense of anyone aforementioned, if you think that you're misreading me)
