If I'm reading the telemetry correctly (https://mzl.la/3bq5oFZ), there are ~6k people who used FTP to download a file in the past week or so. That's not enough users to really justify spending manpower rewriting it.

you should never trust telemetry or analytics to be unspoofed.

You’re suggesting there is a mass campaign to spoof Firefox telemetry and mask high levels of FTP usage?

Even if it's not spoofed, I would conjecture that the set of people using FTP has a large overlap with the set of people who disable telemetry.

im suggesting that everyone i know and thier mother intentionally spoofs any telemetry or analytics they can rather than block it. nothing atypical about it, it is very distinctive to comepletely block fingerprinting analytics telemetry. it is much better to spoof the content rather than block it.

Then everyone you know and particularly their mother is extremely atypical.

have a look around github

the breadcrumbs start here:

https://gist.github.com/MrYar/751e0e5f3f1430db7ec5a8c8aa237b...

https://github.com/search?q=spoof+telemetry

if you know how to do a web search do that. if you cant then sorry about the luck.

The gist talks about disabling telemetry, not spoofing it, and reading the prefs it sets makes it clear that it is actually disabling it.

The github search reports a single repository last updated three years ago, and doesn't appear to even be related to Firefox telemetry at all, as the telemetry appears to be spacecraft telemetry.
