But you can simply add the account data, Google still has a large free tier for free apps.
If you use the map a lot, then this might get exhausted soon, and the cost may explode.
For a seldom map requests the tfree tier might be OK.

So a lot of developers will have to look after more reliable sources then, and this could affect the whole Google Cloud business.
