> I'm genuinely interested what was the show stopper for you

For some people, directly supporting a huge, unethical, advertising company with money is a show stopper.

> when my phone lost support

This is another serious problem: e-waste. My phone will not loose support, ever.

What phone never loses support? I'd expect that cell network changes alone invalidate that claim.

[fsflover]

I don't think that the OP was talking about the cell network changes when they said that the phone had lost support. GNU/Linux phones (Librem 5 and Pinephone) will never loose software support, since they run mainline Linux. Also, Librem 5 has a replaceable modem.

Oh, Purism. The guys who included a separate chip to deny the user the ability to upgrade the firmware, so that they could meet FSF's completely arbitrary requirements for a honorary badge of freedom (see the hypocrisy?), but neglected an IOMMU, so the baseband (or any other device on the bus) can wreak unlimited havoc (see the irony?). Great alternative indeed.

This is false: https://news.ycombinator.com/item?id=26784382 and https://old.reddit.com/r/Purism/comments/pcos2x/would_it_be_...

> neglected an IOMMU, so the baseband (or any other device on the bus) can wreak unlimited havoc

The Librem 5 doesn't need an IOMMU, because it uses separated components, and it uses serial buses (USB 2.0/3.0, SDIO, I2C and I2S) that don't allow direct memory access, so there is absolute no chance of the WiFi/BT, cellular modem, GNSS and USB controller being able to access the RAM or the SoC's cache

Do you think that all laptops are also totally insecure, since they use USB?

"No chance of DMA access"

The USB URB structure have a field named 'dma_addr_t transfer_dma', used for DMA access. I've abused that to chain vulnerabilities. To boot, it is possible to develop an I2C-B2C or SPI bus master which is capable of DMA toward the host memory. Linux 2.5 kernels and later, USB device drivers have additional control over how DMA may be used to perform I/O operations.

Do any of these guys actually read the hardware specs or do any real hardware hacking?

Commadore 64 also hasn't lost support and McDonald's made a new Gameboy game.

Android runs mainline Linux. The Linux phone has no benefits.

My Librem 5 currently runs Linux 6.4. Which Android runs it?

[graphe]

I don't know, Google integrated the mainline Linux kernel a while ago. Probably most of the modern ones.

PostmarketOS fills the plaything niche like the Librium 5 and pinephone do but much cheaper with much better old hardware. Aside from a checkmark of running the latest kernel and hardware switches what can the librem 5 do an Android phone can't do much better? They aren't good phones.
