Personal Comments and Observations
Not exactly. The SDK was available to First Party Dev Partners first - because they had to deliver planes and other items MS commissioned for the launch. In the meantime, the SDK was fine-tuned and then released to General Public, which includes all other Third Parties. The timeline between that release and launch made it really tight for all other vendors to start re-tuning their FS’20 offerings. Some made it - Raul Simbom (FSReborn) is an example. His Sting S4 shows up as Enabled in FS’24 for his previous customers when their library is migrated. But that was a herculean effort on his part. Many of the popular products are, not coincidentally, made by First Party Partner Devs, who obviously had to service their Microsoft sim launch commitments first if they had them.
