This is why Google will forever be behind Apple. Any app that can't be monetised gets killed. Why give Android users a stable ecosystem after all? Fuck the users. Google fucking sucks.
It's more the principal that Google doesn't care about their ecosystem or users. There would be uproar if Apple killed their podcasts app, since it has been around for so long. But Android users are just used to this shit now.
It's not like podcast players are particularly complex to build and maintain, so they don't require that much cashflow. Podbean sustains itself quite well with the odd image ad and AntennaPod is FOSS. I think the problem is more the opposite, since competition is so easy and monetising it would suck interest out of it, Google has no interest in actually competing. Which is why they're trying to build their own walled garden with uploading your podcasts only directly to YouTube, RSS feeds be damned.
