Important note regarding Grok @Bot: Going forward, @SpaceX will use the best back end model for any given task, including Claude Opus 5.5, MidJourney, Suno and other leading APIs. Whatever is most likely to give you the best outcome.

BREAKING: France just voted to tax the internet. French lawmakers approved a tax of €0.055 (5.5 cents) for every gigabyte of data that companies like Netflix and YouTube send to French users. It’s a tax on the companies, not users directly, but the cost could get passed on to subscribers. The vote was 11 to 10, with only 35 of 577 lawmakers present. Supporters say it could raise up to €10 billion a year. The French government opposed it, warning it would hit smaller French companies hardest; VLC says it would cost it over €1 million a year.
Readers added context they thought people might want to know
This amendment to France's 2027 budget bill was narrowly adopted 11-10 in the National Assembly (35 voters present) but is not yet law, faces government opposition, and must still clear further Assembly/Senate steps. assemblee-nationale.fr/dyn/17/comptes… assemblee-nationale.fr/dyn/17/amendem… capital.fr/economie-polit… stephanelarue.com/taxe-au-gigaoc…

‼️ The git, curl and python3 in macOS still trust compromised eMudhra certificates, 11 days after Apple was told. Anyone can recover their keys, so an attacker on your network could pose as GitHub and feed you code. Researchers say macOS 27.2 even wiped fixes applied by hand.
