Then I realize it's even better than before because it demonstrates for a potential employer that you'll push whatever buttons you're asked to in exchange for money, regardless of whether it's good for the user, the internet, or society as a whole.
I wouldn't. Over the decades I've seen many people hire, and later regret hiring, people who demonstrated poor character.
In a more public sense, remember the Bush-Clinton election where the full version of the fabled "It's the economy, stupid" slogan was "Character doesn't matter; it's the economy, stupid." And we see what happened when someone of poor character got power and an intern.
That being said, it should be obvious even to you that the place where one invests one third of their day for years on end defines a large part of who that person is and how they behave during the other 2/3rds of the day.
I remember reading an article a few years ago where several senior ex-Facebook employees were horrified at what they did and were trying to protect their kids from the monster of online advertising. Funny how that becomes clearer once one's income doesn't depend on advertising any more.
As far as "cheerleading for the ad industry", I also built an adblocker, spent 6 figures to test alternative payments, am part of every initiative to make ads better, and have spoken with senators to push for regulation. But you wouldn't know that with the quick character judgement that you seemed to make, which is ironically the actual subject of this thread.
It's a surprise to read that you want to regulate advertising, given your continous criticism of the GDPR and support of data collection in several comments.
What exactly do you understand by better ads and what kind of regulation do you support? Are we talking about yet another one of those "industry successfully regulates itself" stories?
