If XYZ Inc. built gotham with palantir supplying them foundry, palantir can claim to be "just like postgres".
This all matters only if you're actually against gotham / automated surveillance, of course, and believe that it was not happening until alex karp.
Wat? These are wildly different things:
> Say No to PostgreSQL
Sure, if you self-host it, this would be a stupid thing to say.
> Say No to Excel
A little worse: it's proprietary and who knows what it does and where it sends your data.
> Say No to Salesforce
Way worse: they host the data, and who knows what they do with it.
Salesforce, Microsoft, and PostgresSQL contributors aren't bragging about how their products enable lethal military operations.
The comparison to PostgreSQL in particular is very poor in that regard.
