Signal Desktop and Cleanflight are open source.
And sometimes, you have no choice - there's no FOSS alternative to TeamViewer, and thanks to it running inside Chrome, I no longer have to run a Windows VM.
The web based SSH client is published by Google themselves and they use it internally.
> The teams working on Debian, Ubuntu, Arch, etc. have much better security track records than some random web developers who've made an "app".
The way things are, right now, Chrome is much better at protecting apps from each other than my Linux desktop is. If, for example, the Cleanflight or TeamViewer apps were regular apps, a bug in them would fully compromise my account.

Off topic remark about Linux distro security: I really like Arch, but security isn't their strongest suit. For example, they still haven't enabled full-system ASLR, citing unfounded performance concerns, when other distributions did so years ago. Even Windows with all their third party apps has a higher percentage of ASLR binaries than the average Arch system.
They also have no central build system and instead rely on volunteers who build the packages on their personal systems and sign them using their personal GPG keys.
I really want ASLR in Arch so I'll keep complaining about it publicly until it finally happens :-)
