Chew on this:
Under Burwell v. Hobby Lobby, 573 U.S. ___ (2014), the Supreme Court essentially allowed closely held corporations (or companies who have 50% of its stock value is held between 5 or fewer individuals (directly or indirectly) in the previous tax year) to exempt themselves from federal laws they deem to be an affront to their religious beliefs. Sweet Cakes falls under that category according to IRS regulations, and as such, in my opinion, this opens up the State of Oregon/US government to a countersuit. Under the RFRA it states also, “Government shall not substantially burden a person’s exercise of religion even if the burden results from a rule of general applicability.”
As I interpret it, a law of general applicability (which Oregon's Equality Act falls under) is a [religiously] neutral law which applies all individuals in a state, or the United States as a whole. As far as the RFRA goes, some Federal laws are exempt from oversight under that act and purview of the First Amendment, as per the Supreme Court. I must also assume that state laws which expound on existing Federal laws are also covered under the RFRA as well.
If I interpret the Burwell ruling correctly, Sweet Cakes could have (using Burwell as precedent) exempted themselves Oregon's Equality Act of 2007 pertaining to sexual orientation because it (as they claim) violated their religious beliefs, that would also allow them to file an appeal with the Oregon Bureau of Labor and Industries over their ruling ordering them to pay $150,000 for discrimination under Oregon's Equality Act.
The language of the of Burwell ruling stated that for-profit corporations (like Sweet Cakes) are considered persons under the Religious Freedom Restoration Act. It also allows for those closely held for profit corporations to assert RFRA to protect the religious liberties of the owner(s). Also, the government must justify its regulations under strict scrutiny; that is to say, the government must demonstrate that its regulations are the least restrictive way to further a compelling governmental interest. There may be parts of a law that meet that requirement, and then there are parts that do not. This leads me to believe that Sweet Cakes had a legal right to exempt themselves from part of a law they saw violated their religious beliefs.
