I think we're in agreement more than it seems.

Number 3 is especially important I think. It's especially sneaky to make it look like you're endorsing something you aren't or, worse, never even heard of.

As for number 6 I'm no lawyer nor do I even have enough casual knowledge of this sort of thing to know anything about it so I'll take your word for it and if that really is the case then I'd wonder why they're not in any trouble over it yet.

Where we differ here is on what we believe we're entitled to and when I use the word 'entitled' I'm not saying it in the usual "oh too many people think they're entitled to XYZ with free services these days" sense. Maybe "expectations" would be a better word but that's not it either. Yes, I do believe too many people feel too entitled these days especially with free services like this but that belief isn't absolute and I do believe there are some things we as users of any service free or not are entitled to, almost like a web user's bill of rights. Those things, in my mind are:

1. Notice of changes to service and policies

If a policy is going to change or a feature is going to be added, removed, or modified we should get some sort of notice via email, blog post or preferably both.

2. The right of free users to keep their active accounts for as long as the service stays in business

If I have a free Google account I expect that so long as I'm using it reasonably often Google won't decide one day to just get rid of all free accounts.

3. The right to continue using the core offering regardless of feature additions, subtractions, or modifications for any other account type.

So as an Instagram user I should be able to take, post, like, and comment on photos as that is the very core of the product. If one day Instagram has paid accounts I'm not entitled to any of the upgraded features but I should never lose the ability to use the service in its most basic ways because I'm using it free.

Those are the three "rights" I think we should have and even then they're still more like requests because we're still at the mercy of the provider until we pay. But generally, a free service provider who acts in good faith would follow those 3 rules. Now I think wanting the ads to be opt-in is more of a nice-to-have than something we should absolutely expect. I don't think its reasonable because users probably won't take notice at all as it requires effort. But by having it be opt-out, those who care will take the effort. It's really a win-win. Those who care don't have to deal with it while those who don't care get to share the revenue.

Your line was crossed and you left and no one can't respect that. I have different limits and think mine are a little more reasonable considering it's a free service.

I actually just registered the domain 'userbillofrights.org' because of your comment. Even though I don't agree with you here I think there's still a lot I do agree with and I want to invite you to help me write a user's bill of rights and maybe put it out there and get some free service providers to "endorse" it and maybe even try to compile a list of services that adhere to the user's bill of rights so people can see who they're dealing with before signing up. It's probably a dumb idea but I think it'd be fun. We can start with Disqus.
