I have this problem, we could have a lot of branches but only a certain number of environments e.g. dev, qa, stage etc.. So would this tool allow me to create environments dynamically so that I can test each branch standalone.
In a way, I think it's better for open source projects that need money to go the AGPL route. The way I see it with pledging is that you'd be getting companies that are already donating/contributing back to open source projects. Whether this will be more or less than what they're already contributing remains to be seen.
Even if it's harmless, I don't think it's his place to make a decision about whether electronic interference is dangerous to the plane's equipment or not and affect the safety of everyone else on board. The steward on the other hand is completely justified in enforcing/following the airline's (industry?) policy.
