Telecommunications company blocking HNT and Antenna Modification

I have been following Voskcoin quite a while I just have a couple of question that I hope can be addressed:

  1. What are the chances that Telecommunications companies across the globe would block Helium or HNT mining?
  2. What are the outcomes if more people become miners, overall and/or in your area - ie where earnings are heading?
  3. I know that by default, whatever miner we ordered will include an antenna, is it possible to replace it with a stronger antenna like 8dba?
