> This is an interesting topic. If a company does something you approve of (e.g. do journalism) and something else you disapprove of (e.g. make canceling hard), is there a good way to signal both as a consumer? This is also relevant in the context of companies like Target, which has been boycotted by both sides of the US political spectrum for various reasons.

No. at least not as a consumer in the marketplace. That's why people who act like the market creates a good fit for consumer preferences or go on and on about things like "revealed preferences" are just plain wrong.
