That's not because 12 years passed, it's because Heroku didn't innovate or even keep abreast of the competition in that timeframe.
> Cutting off the free tier is in Heroku's best interest. It saves them money and allows them to focus on their current customers.
It cuts off the only onramp they had for entry developers or developers who can't afford to pay their ridiculous prices (I mean come on, $25/mo for 512MB of ram? Is this a joke? It was expensive but understandable when they launched and has only gotten worse while the product has not improved which competitors have blazed past them).
> But it does mean that there's no growth in the product any more, unless they offer something new.
I won't hold my breath, it seems clear they are life support at this point.
