There is no matter of opinion here really, the new part 107 is bad news for those of us who were pilots with section 333 exemptions. Those of us who were operating legally and willing to report our illegal competition were experiencing enormous opportunity during the rise of this technology. Part 107 is going to level the playing field and 'open the flood gates' as it was so accurately put by a UAS attorney today.
Apart from business, I truly believe that this provides an unsafe level of regulation regarding drone operations. The reports of unsafe drone operations have only increased with time, not decreased, and these new laws are not reflective of that. It is obvious to me that they were more concerned with creating job opportunities rather than insuring safe flight operations.
That all being said, we all knew this was coming eventually, and if you were ahead of the curve with the section 333 and your business over the last few years it means you have gotten that much of a head start. I for one have a great reputation in my area and any new flyers operating in the area will have a hard time competing, especially since I also bought all the domains pertaining to 'drones' and 'aerial' relevant to keywords in my area.
Regardless of that, there is something else that will remain the same that is extremely important:
Even though the process has become 100x easier to become a legal operator, this industry seems to attract the type of 'entrepreneur' that would rather stick it to the man than go through proper means. Lots of these cheap operators will remain illegal, and if that is the case I would recommend reporting them to the FAA before they get dangerous. (you can interpret that anyway you like)
The FAA is surprisingly great on tips regarding illegal drone operators. I for one have the local FAA office on speed dial and have seen many a facebook page become suddenly inactive.
