It's all legal and fine, it's just how do you get it approved? You're not actually buying anything, nothing will stop working and no projects will be impacted without the PO. In a large company, this effectively makes it impossible.
The solution is to just pretend you're buying a minimal support contract and that'll get approved no worries.
Furthermore, in large companies, charitable contributions are probably handled by a completely different organization with monies coming out of a completely different bucket than sponsorships being paid out by some marketing department or other.
Every company has some process for buying something and paying for it. They have to. And similarly they have to have someone who, on a regular basis, approves purchases. Most don't have a process or person for approving donations. So at a minimum somebody has to think about it. Whether that's thinking about whether they have the authority to approve a donation, or thinking about who above them would need to sign off, or thinking about whether making donations is a good corporate policy, it's thinking instead of doing. It's a surprisingly significant barrier. Like how it shouldn't matter whether the buy button is reasonably sized and gray or giant and green, but in practice it does. You want to make it as easy and thoughtless as possible for people to give you money.
