As far as I can tell, subscriptions aren't a reliable way to opt out of ads and ad tracking. Look at cars, cable, Uber, Spotify, Amazon prime, newspapers, telecoms, ISPs, etc. They all show sponsored content and upsell services to subscribers.
I've tried putting my money where my mouth is by switching to subscription services for everything and I still have to go out of my way to avoid advertising with adblockers.
I wonder if advertising really is a waste of time and money for the most part, and it's just that the advertisers are really good at convincing people otherwise.
I worked for an ad measurement firm; we developed a causal ad measurement methodology based on a research tool used for observational data in clinical trials. Roughly 1/3 of the thousands of consumer packaged goods (toothpaste, canned soup, breakfast cereal, etc) studies we performed showed no effect of advertising. Another 1/3 didnt have enough of an impact to justify the ad spend (ROI < $1.00), and about 1/3 showed more revenue than ad spend.
Obviously, different industries are likely to show different distributions of results, but CPG companies are the biggest ad spenders, I believe.
