Sure, you're absolutely right. This law, as it is right now, probably (and I say probably, because who has the time to read the fine print?) doesn't affect indie devs in any way.
But there's this little thing called precedent. This can and will be used as a springboard, an established platform, to further litigate against and control the industry. The government is only good at making problems, not solving them.
"Hey, indie developer, I'm with the Department of Service Sustainability. Where's your end-of-life plan form 55-B?"
"I... uh... I'm not making a live service game. I'm really just kind of new at this. I just wanted to make a Mega-Man like, so... I mean..."
"I don't know what that is, but any commercial electronic entertainment product needs a 55-B filled out detailing your tiered end-of-service strategy."
"There's... no service. I mean, it's a single-player offline game. I - "
"I don't know or care what that means. You're making a videogame, right? And you're trying to sell it online, for profit?"
"Y... er... Yes, I guess."
"That means it's an online service. So where's your 55-B?"
"Okay. What do I have to do to get this form?"
"That's your responsibility. Make sure you have a $500 application fee ready when you arrive at the nearest office."
"God. Which is where? Oh c'mon, that's 50 miles away!"
"That's your responsibility. Oh, and there's a $500 notice fee. Make sure you have that, too."
Yeah, no. Screw Ross for trying to involve the government in this shit. He's just trying to be a celebrity, and in 10 years' time, if there even is a games industry left, we'll all suffer for it.
Never give the government a back-door into your hobbies and interests. All they care about is MONEY (how to milk it from you) and CONTROL.
