The claims about privacy are, at best, dubious.

While it's true that there are less opportunities to track you through leaky / malicious apps, "dumbphones" remain, well, phones, with data retention laws in almost all countries in the world (and the subsequent leaks / hacks, see the recent Salt typhoon events for a good example) plus extra vulnerabilities due to poorly-developed Operating Systems.

That depends on what threat scenario you're looking at. If your government wants to track you, they'll find a way, regardless of what phone you're using (or not).

But the privacy gains of not installing a load of third-party apps from a dozen different data-selling businesses (or using an operating system built by the mother of all data-selling businesses) are very substantial.
