1/2 Is it a good "business model" to argue with a person/country which is *giving* you money? We'll see: twitter.com/otmarianna/sta…
2/2 My take would be "no", since those are gifts and you do not argue with people giving you gifts. You can politely reject them though, if you do not like the terms. (Or you can report gifts/givers to police if you believe those are bribes, etc.)
