It was a prisoners dilemma, where the whole industry could be more profitable by cutting advertising, but there was always an incentive to ‘defect’ and advertise your product.
The government banning the ads solved this problem for them.
Without a price change the government can’t benefit because the tax is proportional to the price.
So tobacco companies see a drop in costs, no change in revenue, which results in increased profits.
In the future the government could increase the tax rate, and try to force tobacco companies to drop prices to compensate, which could allow governments to extract the extra profits from reduced adverts. But that doesn’t strike me as the kind of behaviour governments participate in, a little too complicated and risky. Also very likely to have unforeseen consequences as it’s unlikely that every tobacco company was spending the same proportion of revenue on ads.
Not to say that tax rates didn’t go up. Just seems unlikely to be directly linked to the banning of ads. More likely they went up just because they can keep hiking the taxes until all the tobacco companies go bust.

Edit: Tim Cook has made numerous public statements in support of gay rights and being gay. My personal favorite: https://www.cnn.com/2018/10/24/tech/tim-cook-gay-apple/index...

The bigger point is having money doesn’t stop discrimination.

*I get up, I open the door, there's a red dot pointed at my face from a 9 millimeter, 'Put up your hands.'"
One, I remember a study back when cigarette companies were told they couldn't advertise on television that all major tobacco brands loved this because it meant they didn't have to spend any money on these types of ads. I'm sure there are versions of this all over the place in most marketing strategies.
Two, pardon my cynicism, but I'm sure companies model these things out and take action based on those models. No CEO is just like "yes, let's support a social cause." Randomly picking on a brand, but I'm sure Starbucks started flying a Pride Flag because it made sense to do so for the business.
