I don’t think that migration to other blockchain could help. We did already in the past and there we are with the exact same problem. You can read here:
And also I think that more wide ETH community than any other new blockchain can offer much more solutions like batches, L2, ETH 2.0
The moving was a painful for sure, we still have requests to convert useless SJCX tokens to STORJ, even they are deprecated and not used since 2017 and converter closed in 2019.
We do not want to have this again, unless there would be a significant move from the ETH to other solutions (If that would happen, I believe the fee will become a normal again 
).
Thanks for your feedback regarding communications, I forwarded it to the team. I hope that we moved further with communications over years though.
