Playing games on emulators is a rather... well I won't say unethical because emulators are a good way to play games that are no longer marketed. To an extend I feel the same way of movies, comics and other media. Some regard it as piracy and should be illegal but these pirates in question often dig up treasures from our past that we can't buy or access today.
But I will agree with you that giving away Sonic 2 for free is kind of scammy. I remember when Sonic Mania was delayed for Steam released so they gave Sonic 1 away.
That's "nice" I guess Sega but we already have those games. You're practically giving us nothing with sincerity here.
