Telemetry and spyware are not the same thing (irrespective of whatever Firefox is doing). There is a big difference between tracking to try to understand how users are using a software or getting information on bugs and crashes, and tracking with the aim of monetizing personal data.
I'm personally not crazy about telemetry implying information is uploaded to a software provider, but from experience I know that trying to create a software without getting in-use data is basically flying blind. You cannot expect users to tell you about problems or bugs they have, they will just stop using your software and you will never know why.
