Postman which I thought worked locally on my computer, is down

not possible once you sign away your allegiance to a VC

sign in, you mean.

sign away means getting rid of vcs.

I read that as "sign your allegiances away from their current counterparts (e.g. the user) and towards the VCs instead".

There seems to be a common theme here. Some project gets traction, it works very well. Then they got VC money and the project turn to crap for the community. Not all VC project, but seems to be common theme. I also aware that devs need funding to keep a project going for the long run. Are there any better alternatives for funding now days?

Not sure if this applies to Postman specifically, but I think a lot of software projects start out largely as hobby projects, and might not have even had an ambition of making serious money out of it, and as such there's no reason to be hostile to the community.

Then a VC fund gives these developers a dumptruck full of money and expect returns immediately afterward. Something like Postman likely doesn't make a ton of money unless they're doing something anti-consumer like selling data.

I understood it as giving it up, not getting rid of. https://idioms.thefreedictionary.com/Give+It+Away
