The network effects of sites like Facebook, YouTube, Google, and Twitter oftentimes mean taking the ethical stance and "not being part of it" can create serious harm to your business/career/vocation.
There's a reason Instagram Influencer and YouTuber are, despite the sniggering of many people, real jobs that earn tons of money for those skilled in plying the craft.
This is especially true in a lot of developing countries, it's so bad Facebook is effectively considered the internet in many parts of the world. Just look at their ridiculously anti-competitive internet.org/free basics service which is quite dangerous due to the extreme network effect it creates by blocking nearly all smaller 3rd party websites for most users on that service(even though there are some search engines available they will be of little use unless a user can access the pages in the search results).
Every tool available should be used to fight Facebook's world takeover plans, including Ad-blocking aggressively. In cases where it's not practical to entirely avoid Facebook the most ethical option is to aggressively block all their monetization paths so as not to further their dangerous expansion ambitions.
I'm currently in the Philippines and a lot of businesses don't have their own web sites and just have Facebook and Instagram pages.
I just browse Facebook without logging in but it has a huge dialog asking me to log in.
Of course there are exceptions to the rule but most people are not IG Influencers and Youtubers so opting out of these social media services are not as painful.
