I agree with you even though I’m only guessing at the episode you’re talking about and I have no idea which of the two Vortas he was.

(It’s the Ferengi hostage exchange episode, right?)

Look up “Topsy the elephant” (among other things).

The name made me think it was made by the same company that makes these.

Trust me, you don’t want to be trying to maintain legacy Jython code at this point, let alone use it for anything new. All the “normal” Python infrastructure like Pip etc. has moved on and broken compatibility, so you’d have to find and maintain locally the last working compatible version of every single package you use. I suppose you could use Java libraries, but the impedance mismatch trying to use LBYL explicitly typed stuff in EAFP python is terrible. It’s just a horrible mess.

is Jython still a thing?

No. (Source: I had to try to keep its zombie corpse shuffling along at my last job.)

Only the latter definition is valid!

You can still view the source code. That’s what open source is.

No, it’s not. It only counts if it provides the four freedoms listed here:

• The freedom to run the program as you wish, for any purpose (freedom 0).
• The freedom to study how the program works, and change it so it does your computing as you wish (freedom 1). Access to the source code is a precondition for this.
• The freedom to redistribute copies so you can help others (freedom 2).
• The freedom to distribute copies of your modified versions to others (freedom 3). By doing this you can give the whole community a chance to benefit from your changes. Access to the source code is a precondition for this.

And before you say “but that’s the definition of ‘Free Software’, not ‘Open Source’,” even the latter, misguided as it is, at least still requires freedom 0!

There is no such thing as “conditionally open source.” The license terms you describe are just “not open source.”

If they actually gave a shit about commercial entities contributing back, they should’ve gone AGPL3. This is just a money grab and yet another example of how permissive licensing isn’t good enough and everything should be copyleft.

!selfhosted@lemmy.world is one of the biggest communities on that instance (and therefore also likely one of the biggest in the entire fediverse, since that instance is so big). In other words, I think you might be right, LOL.
