It’s not really ‘their’ forum, although they host it. Given the amount of posts there are I doubt they are even interested unless they start the topic or someone actually pings them over a support issue.
I suppose this is the real debate.
‘Security and Firmware updates’ maybe that should be the title as it will always apply rather.
Qualcomm support OS updates for a while, hence Fairphone’s own efforts for A9 on FP2
Wouldn’t it be an idea to change the title to something like
Fairphone and SoC Firmware Vulnerabilities as that seems more to the point.
I.e. it’s not really a question but a concern that you have.
Also can you point to where such outdated firmware on the previous FP models have caused you concern. Else the topic can be seen as just a wind up.
This is not just an FP4 issue, though you mention this model.
