LOL first of all, it has nothing to do with "holding hands". You alluded to something and I wanted more clarity... and after asking more questions, the actual facts comes out after all.
So in the end... you paid $300USD to get the Eplus app and the PC Link (which standalone costs around $200ish) to install some modified firmware to derestrict your E-bike; if that got you what you needed, then you got what you needed. That's perfectly fine.
For the benefit of others, they can also do what you did - OR instead use ST Unlocker (with the $33USD license), official Shimano E-Tube app (free), official Shimano firmware (unmodified and free), and nothing else (no need to buy the $200 Shimano SM-PCEx) and get the exact same results.
