I find TrueCaller very usefull. I used to get sooo many sales and robo-calls a day that I seriously considered just getting rid of my phone. Now they get automatically blocked or I can just put them on a profile that they ring silently and hang up immediately. I get that this can be dangerous for journalists, but shouldn't they maybe investigate alternative ways of contacting sources privately? Mobile numbers are not…
This suggests some fundamental difference compared to the US which maybe should be changed instead of a third party band-aid app with lots of problems, but again I don't know this difference and thus will refrain from judging...
