what is copyleft? why use it?

right to repair (= right to modify)

good for business (competition, trust)

good for advocacy (better for user, society)

what rights must you receive, and give?

derivative work obligations - yes, but...

gives you rights even if company doesn't "modify"

"you must give the recipients all the rights that we gave you"

how does copyleft work?

AVM - took a while, but now we know

"the scripts used to control compilation and installation"

examples (good and bad) on Use The Source

what does this give us?

actual, practical ownership of your devices

crucial for longevity - lots of examples

SFC knows where we are at is not good enough

we want more! (and we work hard to get it!)

you can run a good business on copyleft

shipped in hardware, subscription, libre non-gratis

build a society where the currency is not privacy invasion

healthy open source projects

use copyleft licenses - encourages contribution

diverse copyrights, no CLA (Producing OSS on this)

critical mass is intrinsically motivated

contributors use it themselves (see also ^)

home is a non-profit charity (ideal)

ways to promote open source

get involved, consider NPO support/work

push back on no copyleft (no Linux, really?)

watch for how to help the business (queue Linksys)

keep your copyrights

Use The Source
