I gave it a thought and decided that I'm not afraid about the data that I know that others know (or may know) about me. Well, based on the fact seeing any actually helpful advertisement is an extremely rare occasion (just my experience), which usually requires explicit training of a suggestion engine with multiple rephrased queries explaining what I want to see, I'd say either they don't know any much, or the association part is not yet here. Not that it matters, though - that could change in future. What I'm actually afraid is that there is some data I'm not even aware others know about me. Or, more specifically, data I don't want others to know about me, that could've somehow leaked despite lack of my consent or even me being informed. E.g. I know that my phone sends various data to the third parties, that I've authorized it to send. I've evaluated it and had actually decided that I'm OK with the pros/cons. However, if, for example, that phone somehow eavesdrops and sends an audio stream that I've never consented to share - that would be scary.
