  Unfortunately you've fallen victim to years of anti-GPL propaganda and FUD. A 10-liner GPL Python script is not going to "infect" an org with 20 million lines of closed source code. Suggesting that it's possible, even "in theory", is absurd.

Unfortunately, intention is not how law works. The GPL is a legal contract, and how much of a company's IP will come under it will be determined by a judge after lots of expensive litigation. If a suit is filed they will pick apart every line in the license, subpoena every change that was made in every version that someone could claim "was distributed" (available at a public URL?), every email that was tangentially sent, every bug that was filed, every document written, etc, just to determine the extent of what is covered. If that sounds excessive and you haven't heard of it happening, that's because no one wants to go through this and would rather settle than spending the money and effort on defending themselves. To understand the potential, look at https://en.wikipedia.org/wiki/Google_LLC_v._Oracle_America,_....

The GPL purposely weaponizes source code in a way that other open source licenses do not, and personally I would rather hope that people decide on their own to release their changes than invite the lawyers into my code. Using code licensed this way is okay for projects that are already 100% GPL or aren't worth owning.
