Sam is always shitting on others. For years he has been screaming how bad PostgreSQL is compared to MySQL. Until getting silent about this topic for a few months and then launching PostgreSQL support. Seems he had to realize than the market for PostgreSQL is too big to ignore.
No it isn’t normal, its just this one person. I don’t personally find this language particularly appealing, especially for a serious discussion on technology. But hey, its a free country, they’re a startup and its one way of grabbing the scarcest of resources: attention.
AGPL seems like the right choice to me. I’m tired of companies like PlanetScale taking PostgreSQL, building a business on top of it, and then acting like PostgreSQL is theirs to control.
Just launch the product and let it speak for itself. The constant need to take shots at competitors comes across as pretty childish.
