I run a geocoding service for Australia specifically (https://geocodeplus.com.au) and a lot of people I talk to are completely unaware that they're going to see a x10 change in what their forward/reverse geocoding is going to cost them.
Also, it's a lame excuse because this affects paid users such as yourself who have nothing to do with the abuse.
In Google's defense, a hobby project wouldn't need 750k requests a month. At that point it's more than a hobby. But, the 28k limit is low.
Though, Mapillary is quite interesting but their pricing model is not really comparable to Google's one: https://www.mapillary.com/pricing
Microsoft invested in it, released a product and the product wasn't as good as the market leader. That's not predatory.
There are several competitors, the issue at hand is they have an inferior product. If your argument held any water, literally everyone would use TMobile because they are so much cheaper. Reality is, a products quality matters and Google Maps were both more cost effective AND a better product.
We're going to need a bit more detail from an account that clearly has an agenda.
Edit: If you meant that you wanted more detail about my antitrust complaint, I contacted them via the antitrust email address. They took a while to call back, but not as long as Google took to get me that Maps quote...
I'm seeing my own costs, for a site which I run on my own, rise from $1,500 / month to around $30,000 / month.
Their rationale is essentially that they did not want commercial users abusing their free tier. Before this change, they had been reaching out to such entities individually, offering their 'premium plan' service.
The pricing for the (old) premium plan was remarkably similar to the new pricing which now applies to everyone.
This pricing change has ended the era of Google Maps mashups / hobby projects.
