@RTN - Yes, there is a subtle, but very real difference.
Donate: to contribute to a public or charitable cause
Dedicate: given over to a particular purpose
When the Dubs donate something particularly $$$$$ it has no stated purpose and can be used however the recipient sees fit. Even to buying cases of expensive whisky for their own personal use.
When $$$$$ are given under the dedicated condition the governing body members must use it for the purpose given, and nothing else. That is why they promote donating $$$$$ without putting a particular use in writing with the given $$$$$. They can line their own pockets that way.
