You can find someone from Bitcointalk who has paid the monthy subscription and then asked him to send you the data you need for $5 or more, so if you do not want to use that data on a daily basis, you will find some of these cheap ways.
Data analysis is mostly for advanced users who know what to do with that data, so 900 is a pittance for them.

In general, Glassnode analyzes are not 100% accurate, and a sponsored subscription does not mean that you will get accurate results.
