I'm not a first hand observer, but I was certainly around and following the issue at the time. My impression was that a lot of people
watching the issue got upset. I never saw anyone from NeXT or the FSF complain about anything. Just like today, there are people who think that Apple are evil because they don't embrace software freedom. Similarly there are people who think that the FSF are evil for not letting people do whatever they want. To be honest, the acceptance for software freedom as a legitimate idea is far more advanced today than it was back then, and you see how much vitriol is spewed about 'zealots' and whatnot.
To be fair, I don't think Apple was ever interested in software freedom. This is pretty obvious from their actions since that time (moving away from utilising software under the GPL). But I've never heard anyone other than developers complain about it. From a business perspective, it makes sense -- a license is a license. You don't want to pay the price, you don't get the license. I got the sense that Apple's management understood this principle completely.
From the FSF's perspective, they got an Objective-C front end for GCC and they were particularly happy about that. It was a kind of triumph because the GPL did its job. Objective-C programmers had a free platform to work with, which never would have happened if GCC had not existed and was not GPLed. One can argue that these days more and more companies understand the benefits of open source development and might contribute large pieces of code willingly, but that certainly wasn't the case in those times.
I would also be interested in first hand views, but from my perspective, it was always a non-issue.
