Yeah, you can either assume your worldview is the only one that exists, then seemingly not understand why certain decisions are made or how things work elsewhere, and everything looks stupid and doesn't make sense to you. Or you can try to understand things from other perspectives, and maybe actually understand the reasoning behind it and what it means.

What is and isn't personal data is subjective, regardless what "truth" you believe you're sitting on. I won't claim you're right/wrong as there is no such concept for subjective things, I suggest if you want to understand instead of wave your hands around or whatever you're doing, you'd try to see things from another's perspective and forgo dogmas.
