I want to expand on my answer. Many pilots also have grown to a certain lifestyle that depends on a steady 10-15 hours of OT and the expenses that come with it. Not a great reason, but it's there.
One of my main reasons for not being against OT pickups is the company is not trying to save costs, it's trying to take permanent concessions. For example, we've had two bases full of pilots getting released a month at a time, on full pay guarantee. Why not offer a leave of absence every month for these bases? The other two bases have been zeroing out on reserves for the past few months weekly, while again we have had 2 bases full of pilots being released for the full month, who are then able to pickup OT on their days off. Why not offer any TDYs? None of it makes sense if a company is actually trying to save money, so I'll continue to operate as normal and pickup as I see fit until they actually come to the table with realistic cost savings measures.
