The Patreon licence is functionally the same as Advanced Edition. Once you’ve had the Patreon subscription for 3 months, you get to keep it forever. So the actual price difference after that 3 months is negligible (but yes it is a little higher when you account for taxes)
The reasons for the restrictions are documented here: Regional Availability - TLDR: if your country is restricted, it’s because your government has excessively costly tax policies for foreign businesses. So we bump it over to Patreon instead, but the price is a little higher because the fees we end up paying are higher.
