Quite.
It’s why I lock my devices down as tight as I can get them, limit what they can do to an annoying extent ¹, use as many offline apps and services as possible, block access to any ‘conveniences’ that I don’t need, block ads and trackers and all manner of unsavoury elements, don’t sign up to anything anywhere ever (this is my only OLP in the entire World apart from a number of email accounts for various purposes not dissimilar to the arrangement outlined above for personal/professional/public reasons).
And why my computer platform of choice is Arch linux — the only things on my machine are the things I put there myself, by hand.

¹ Seriously … on a daily basis even I get annoyed at how many hoops I have to jump through just to get even the simplest of things done because of all the restrictions I put on things ².
² On the plus side, I lost a phone over a year ago, that was never returned but, in the meantime, I can still log into the associated account because, after whoever found it figured out how to unlock it in the first place ³ and successfully cracked the PIN they were then faced with a standard password login screen requiring a twenty-four character alphanumeric-plus-’special characters’ code … and even if they somehow managed to crack that, it was followed by yet another PIN entry screen (twice) before they could get to the home screen — I imagine whoever found it simply gave up and factory reset it … which is all I care about ( can get a new phone but not a new life).
³ Not entirely unintuitive but an unexpected step nevertheless and, therefore, a way of slowing them down right from the outset.
