You're partly correct: the source code for VSCode is available. You can build an application called "Code -OSS" from the source, or you can download someone else's build (called VSCodium). Microsoft's build contains telemetry and some extensions that are not open source, and so it is licensed under a non-OSI license.
Thanks for reading and commenting!
Sublime is not at all open source.
