You are equating a voluntary act of creation, committing to a github repository, to an act of theft and a violation of private property rights. You have gone off the rails.

Anyone using github activity as a proxy to evaluate a developer's quality of work needs to be aware that they are using an imperfect heuristic. It is extremely easy to game. This is not even remotely similar to property theft.

If you find that your shortcut heuristic is no longer reliable (which is inevitable in the long run) then you need stop using that metric and find better, more accurate signals to evaluate a developer's contributions. If the green boxes aren't cutting it, you need to do the work instead of taking a shortcut. It's as simple as that.

 Leaving unsolicited the personal attack to one side.  You are not making a credible argument.  The topic was the attack on testnet3.  And you've created a false equivalence.  It comes accross as a bad faith argument that is not productive, so I'll thank you for your opinion and we can agree to differ. 

 Ha! Very well. We are communicating ineffectively on different topics.

fwiw testnet3 was being abused by scammers. They found a way to extract value from any proof of work network so the utility of testnet3  to the bitcoin movement as a whole had fallen below zero (this is a subjective value judgement). It was overdue for a refresh because it became too hard to get new coins.

Fabian Jahr (who is awesome btw) took it upon himself to lead the charge for a new testnet4 without the protocol vulnerabilities of testnet3. He is continuing that work, most recently with a project to fork off chains of 0-difficulty blocks mined by scammers on testnet4. This last project won 3rd place at a hackathon I participated in. 🤙
