I'm of no interests to secret services whatsoever
Yeah, that's not up to you to decide. Someone else will decide that and if your phone was at the wrong place at the wrong time and someone misread or misinterpreted some data you're going to be the guy on the floor with assault rifles pointed at your back and your family screaming around you. Better hope your realize the masked men are the cops so you don't struggle and get shot.
It's not like those doing the monitoring are certain to be competent or even guaranteed to be sane, and with signal-to-noise ratios being what they are and the extreme rarity of actual terrorists you can be sure that most hits will be false positives. Other people 'of no interest'.
Intent DOES matter to me and I do not think that any government in western democracies would dare misuse this power for oppressing people.
Oh, right, because we're not voting any representatives of ideologies that have shown no such restraint into power in Europe. Oh, wait...
So if you want to keep from being 'of no interest' in the future, better keep from saying anything that could possibly piss off communists, neonazis, religious fundamentalists or anyone else who might possibly wield power in the future during the rest of your life. The archives are going to remain but the intent of today has no binding power over future rulers.
