The actual post mentions the following:

> We’ve designed our telemetry system to collect data on “events”. An event is essentially an action, like: Finishing our in-app onboarding, Unlocking 1Password, Creating a new item, Filling an item in a website or app.

> We won’t be collecting your saved passwords, passkeys, usernames, and any URLs associated with your items. Your private information is just that – private.

With it also being opt-in I dont see an issue with collecting basic numbers for how often people use the plugin or app, as long as they're telling the truth, I think it's fine.
