Hello,
I think anyone participating in Fritzing “in the open source way” adds much more value to the project than the 8 Euro. Compared to time it needs to get involved, the small payment is a steal.
And of course we don’t want to exploit volunteers. People have various reasons to participate, and if money is your intent, this might become possible now, too. I tried OpenCollective (a way to collect funds and reimburse contributors), but at that time, half a year ago, participation in Fritzing was so low, both in donations and contributions, that it was simply not worth a further thought. Forum subscriptions where broken, as Fritzing email service changed their conditions, and over weeks nobody noticed, with more than ten thousand users who never received any activation email, just passing on unheard. Speaking of, I actually went to the forum not to discuss this, but fix the login problem some users experience with the forum
