I have historically gone with PostgreSQL and had no complaints. The licensing issues concerning MySQL also give one pause (Oracle are greedy bastards who will use any excuse to extract money from captive customers, so depending on their properties is to be avoided). Having said that, these days, SQLite is probably sufficient for many workloads and has the advantage of not requiring a database server.

Is there any information about this that’s not a video?

The EFF (in the US), Open Rights Group (UK) and similar digital-rights groups elsewhere. If you’re in Europe, some countries have a Pirate Party who are in favour of digital rights and against intellectual-property absolutism.

If this succeeds, won’t it set a precedent making emulation of proprietary platforms in general illegal?
