Firsty, no one is making up anything, if you read the OP then you'd see that I was asking a question and not telling everyone my opinion. How can you just assume that unbalanced egg hatches is just a bs theory when there is no concrete evidence either way? Yes it could have been a coincidence, but it also could be true. If you hatched over 50 10km eggs from a rural area and got nothing but sh!t, but then hatched just one 10km egg from a big city and got a Lapras, wouldn't you assume something? It's obviously way more likely that the big cities will spawn way more of the Snorlax's, Lapras', Aerodactyl's than a rural area, so why is it so asinine suggesting there is also a better chance of getting better Pokemon in eggs as well?
Are you even aware that you are implying that niantic added a secret "feature" with the sole purpose of screwing over people in rural areas, punishing them even more while they are already being punished with far less gyms and pokestops?
Do you understand how "asinine" (your word) the implications of what you are saying are? You say that there could be a secret feature, and if it is revealed, all players who live in rural areas will be REALLY angry and annoyed, and many will stop playing out of frustration and
some players will demand their money back because niantic screwed them by giving them inferior incubators.
Now that i think about it, yes, the word asinine really sums it up.
If the weird hypothesis is true and gets confirmed, it could even destroy niantics business model because some players will be so outraged that they will petition google and apple to remove pokemon go and its updates from the google play store and the apple store.
This would be a screwup so big that it would go down in niantics history as niantics version of samsungs exploding galaxy note 7 phones. Heck, the pokemon company could sue niantic based on the damage caused to the brand as a whole by niantic giving players the message that they despise and actively discriminate against a section of their player base, namely all players living in rural areas. For the same reasons, the owners and shareholders of niantic could first fire and then sue the CEO and all employees involved, because a case can be made that they actively and intentionally tried to undermine the company from the inside.
Those are the implications of the hypothesis, and that is why it is a dumb hypothesis. There is one key difference between the samsung desaster and the niantic disaster that you are implying: Samsung accidentally shot itself in the knee, but you are implying that niantic is doing it INTENTIONALLY.
Just to again point out the flaw in the hypothesis i will come up with my own hypothesis.
Starting next week, the disneyland and disneyworld amusement parks will charge asian people with an additional 5 dollars and dark-skinned people with an additional 10 dollars. Or force visitors who are deemed unattractive to wear disney-themed masks to hide their ugly faces if they wish to visit the park.
Distriminating against and/or showing disdain towards some of your own paying customers is a really big no-no, in just about every industry, but especially in the entertainment industry of which the gaming industry is a part.
So of all the unlikely hypothesis you can find on the internet about pokemon go, this one gets the award. I award it the gold-plated tinfoil hat first class for being so outlandish, it may even be illegal for niantic to implement such a thing. As in, against the law, at least in the USA but in quite a few other jurisdictions as well.
