Most engineers should be able to make that in an hour. Heck, I'd be happy to pay that myself personally.
Given the amount of money in tech, and how critical OpenSSL is to the internet, nobody should even be worrying about costs. The only question should be why every major tech company isn't already writing them a $xx,xxx check.
if this were a Dutch organisation (and I could spare that kind of money ...), I could either fire up my online banking and transfer it without any costs, or use the (slightly easier) iDEAL option and it'd cost them about 50 eurocents + 0% per transaction.
not even just for the Dutch btw, since recently, if they have an IBAN bank account number, you can just transfer money there (well, not to the US, apparently, but in the EU, parts of South America, Africa, Asia, ..[0])

Primarily because it's not tax-deductible. I try to restrict my charitable donations to things I can deduct.
The other reason I don't is that I'm not convinced it would be used effectively. They shouldn't be using small donations as their primary source of funding, they should be going after huge corporate supporters.
I'd be happy to donate $100 if it were tax-deductible and if OpenSSL committed to making the minimal effort of reaching out to major tech companies for substantive funding.
