Merely excluding him from further involvement is insufficient IMHO. If Matt has any equity stake he should be bought out. However that may simply not be possible depending on the legal structure of the entity.
The very first PM I ever sent was regarding a subscription to the magazine. I thought it would be a cool physical item to have around my living room and start a conversation with.
I held back on purchasing a subscription due to the ridiculous wait times. From what I hear the company fails miserably at delivering on any kind of reasonable schedule.
I decided to go with Casascius coins instead, so happy I did
I will never support that magazine, simply for the reason D&T gave. Matthew N. Wright will benefit regardless if he has an active role or not.
He will receive gains on an equitable stake, or he will need to be bought out.
Either way, you will end up supporting Matthew N. Wright if you decide to support the magazine in the future.
