I guess it depends what your threat model is.

If you don’t like advertising, then you’re just piling a bunch of extra interests/demographics in there. It’ll remain roughly as valuable as it was before.

If you’re concerned about privacy and state actors, your activity would just increase. Anything that would trigger state interest would remain, so you’d presumably receive the same level of interest. Worse, if you aren’t currently of interest, there’s a possibility randomly generated traffic would be flagged by your adversary and increase their level of interest in you.
