What I don't understand about the Globee funding proposal is as follows:
Globee is a for-profit company that is accepting donations to implement its payment processing system.
Globee is putting up half of the capital and asking for the remaining 50% to be donated by the Monero community.
Per the proposal, Globee is going to recover their full investment first.
After Globee has recovered their 4500 XMR investment, subsequent recovery will be split 50/50 between the Monero community (redeposited into general donation fund) and Globee for the next 9000 XMR.
All further commissions that Globee attains will solely be profit for the company.
So, Globee takes an equal risk to the Monero community, but their risk is mitigated first (their 4500 XMR is recovered first). Furthermore, they make potentially a significant return on investment, whereas the Monero community donators do not achieve that benefit at all.
Can someone please explain to me, why at all such a proposal should be funded?
Because it will benefit ALL hodlers of Monero if it goes ahead.
Logic says a small proportion of your stash to improve hugely the value of the rest is in everyone's interest. So far this has been Monero's strength - that is, its community is prepared to back it, with no premine etc. it is entirely voluntarily funded.
This is part of why Monero is so admired.
