EMMC in phones has a finite lifetime and dies after a few years of use. That it is not mentioned in the article tells me everything I need to know about its seriousness
Modern phones typically use TLC or QLC within a inch of their physical limits (signal to noise ratio), thus qualified typically only up to 500 FDW, which translates into several years of use.
There are other mechanisms at play which further degrade this number, such as WAF (write amplification) and others
That consumer rate isn't datacentre use, but not every task is write-to-persistent-storage intensive. You can also replace the sdcard and write to that instead if this is a worry (that's what I've been doing on my phones since I use them quite intensively; maybe that's overkill nowadays idk)
