It is definitely good to have a choice between OEM and aftermarket parts. That is important! I am willing to bet that if GE allowed aftermarket replacements, the majority of customers would have still chosen OEM replacement parts.

For example, if my Nintendo Switch controller breaks, I will not even hesitate to get an official Nintendo controller. However, it would be nice to have aftermarket controllers work. However, if for example my IPhone earbuds fail, I would hate to not be able to use spare earbuds I have lying around. If my Macbooks trackpad fails, and I see the choice between using a compatible aftermarket trackpad or a genuine Apple trackpad, I would get a genuine Apple trackpad. That is my choice. Someone else would want a cheaper option, and that is fine.

Now, I could see the angle of wanting to force customers to choose GE replacement parts. Less support. They will be able to diagnose or troubleshoot issues without considering aftermarket compatibility issues. Also, yes, they will have another potential recurring revenue stream!
