I always liked Waze but I don't like Google. I've been blocking as many Google domains as possible but still kept some unblocked just to use Waze (and YouTube). Google changed something, Waze stopped working, I switched to Apple Maps. No regrets.
There are a more than a handful good and active German subreddits. Especially finance-related one like r/finanzen (113,151 readers) and r/mauerstrassenwetten (109,592), or subreddits like r/de (480,614), r/600eur (33,871), and r/germanrap (22,459 readers).
But I agree with you and personally spend most of my time on reddit on international subs. But it doesn't make sense for a German to spend much time on r/personalfinance for example because it's too US-centric. That's where r/finanzen (and r/mauerstrassenwetten (like r/wallstreetbets)) is the better place.
Reddit launched an International Ambassador Program a few months ago[1] and they are paying German power users 20 EUR per hour to create German niche subreddits + 250 EUR bonus for each launched subreddit[2]
