Hopefully they don't start letting plugins show video ads.

Well, with Firefox people were complaining about the removal of ALSA support, with the reasoning that people who liked that were also likely to have telemetry turned off. So a downside might be that your usage patterns are not taken into account when using this or turning off telemetry in regular VSCode - though I'd claim that that is to be expected and completely reasonable.

To me, that's a feature.
