And how would it financially change the current situation?
You now have a license which covers SM up to build 2091, which can be used forever.
If you want a newer one, you are kindly asked (hinted) to further support developement team for their on-going efforts to improve the tool without any functional disadvantages or features being locked.
With “Early Source”, you’d probably have $0 access to an way more out-dated version of SM.
Or do you expect those Early Source to just be max 1 year old so you can go on upgrading forever without any charge? Or would you be fine with the approach Adobe was taking by open sourcing Photoshop sources from 1992 to prevent your intended kind of parasitism of using “nearly up to date” versions?
Happy you, if you are weathly enough to not need to earn money with your every day work.
That said, we should be happy about those remaining trustworthy companies, which build applications which only do what they are intended for instead of being honey pots to collect all sorts of user information or being used as advertisement plattform primarily.
ST and SM don’t collect any telementry (except some crash dumps) and do not follow a selling user data bussiness model. That’s what I love them for!
IMHO we are living in a dark age of pseudo open source software locking in users to certain platforms to collect all sorts of sensitive data in order to sell them.
You’ll always pay!
Open source is not a solution for everything. Just have a look at all those hundreds of thoughands of dead projects hanging around out there. There are a couple of platforms which benefit - sure - but those are some popular minorities.
