It's really funny to see third world freeloaders seethe in the comments about this. Heroku is a great service that deserves the money, and it's not your ticket out of poverty by freelancing online. The free tier being removed means less Ukrainian / Indian spammers and bitcoin mining attempts, which means more resources for the paying quality clients. Thanks Heroku!
Why is it so important to you to identify the third-worldness of the freeloaders you're referring to?
It's a bit unusual. Is identifying them as "freeloaders" not enough for the purpose of what you're saying? It's like... bringing recognition to the fact that some of them are trying to escape poverty via whatever means necessary, but then not actually following through with the moral implications of that.
