Yes, this is a very serious error for bitcoin. When bitcoin became very slow, its transactions began to hang for 200,000, and commission fees for its conduct increased enormously, the #DevelopmentTeam for a long time was inactive, because it did not want to change anything, including its scaling. And the popularity of bitcoin because of this began to fall. The full implementation of SegWit completely did not solve this problem, and the network of lightning actually comes from outside and is not an idea of developers. In fact, bitcoin lost its popularity due to the position of the #DevelopmentTeam , in which there was no pluralism of opinions.
