You can't generalize but most often that is the case. Having said that I'm surprised nobody brought up maybe the most important factor: sunk investments.

If you have a brand name and credibility at stake, if you have customer liability, if you have built significant the features and infrastructure, if you hired the people that run and maintain those, if your revenue depends on current status of your product... We can keep going on but, you have to take extra actions and caution as you introduce change. That means additional complexity.

However keep in mind big companies can benefit from certain types of barriers to entry such as regulation that provide them efficiency over small companies. For example US immigration policy favors big companies, and IMO GPDR will do so as well.
