My tech philosophy:
Use #FOSS for any situation in which viable FOSS exists. Only use proprietary if none exists or do without.
Use software adhering to https://openstandards.nz
Local (in country) is better than off-shore, though this is somewhat price-sensitive.
Social media:
Open and decentralised (#Fediverse) first. Closed and centralised second, if at all.
Governments around the world (especially in my corner of it) should adopt this philosophy with extreme prejudice.
