"Se registran 367 votos en pro, 0 en contra y 1 abstención para el proyecto que expide la Ley Federal de Protección a la Propiedad Industrial y abroga la Ley de la Propiedad Industrial, que integra la legislación relacionada con el #TMEC. Queda aprobado."
Google translate says:
"There are 367 votes in favor, 0 against and 1 abstention for the project that issues the Federal Law for the Protection of Industrial Property and abrogates the Industrial Property Law, which integrates the legislation related to #TMEC. It is approved."
It seems like TMEC refers to harmonization with US and Canadian laws, so given that it is not illegal to install Linux there, I'd be skeptical that this makes it so in Mexico.
When I looked for non-Twitter information, I found stuff that says the criminal penalties are for unauthorized decoding of encrypted satellite TV, stuff like that.
It appears to relate to laws being passed to enact the successor agreement to NAFTA. If you google the Spanish part, you will find more information. I don't know if Mexican bills are freely available on line though.
I did Google it and found the bill and have been scrolling through the translation for awhile and have yet to find a section about Linux or anything like that.
