I'm not sure why this is hard to understand. Your lens is about BM making contributions to anti-gun politicians. Their lens is about making contributions to a powerful Senator that they have to deal with and the House Member for their District. I take it that in your professional career, you have never had to deal with the impact of government policy on your business, the livelihoods of your employees, etc.
Take Wyden, who I have had dealings with and despise. He is the ranking member on Senate Finance. I have had to talk to his staff about a tax credit that could have an enormously positive impact on the livelihoods and job security of the 1400 people that work at my company. I don't have the luxury of turning my nose up at Wyden, whose politics I despise, because my job is to protect the jobs of my fellow employees.
So, Benchmade in trying to protect their business from things like higher tax rates, or by trying to mitigate the impact of the Base Erosion Abuse Tax on their export earnings, things that the corporate officers have a fiduciary responsibility to the owners to do, will, by necessity, have to interact with him. And to be heard, they have to pay him. The fact that BM has made contributions to their powerful senior Senator and to the Representative from their district says NOTHING about their position on guns and 2A. It says that they recognize that under US campaign finance and lobbying rules, you have to pay to play.
As I pointed out earlier, other companies, like Magpul and Weatherby, when faced with an overwhelmingly hostile political environment and lack of politicians that represent their views and interests have moved. Perhaps this incident will spur such consideration by BM. But the fact that they have made the obligatory payments to the Dem pols that run Oregon says nothing about their 2A position.
