In general, no, but its going to take awhile to have enough information for people to understand what is happening. All the information that people have now is outdated. Practically every average EV made today has different chemistries, thermal management strategies, and bms than the average EV 5 years ago and 10 years ago. The Nissan Leaf went into production less than 15 years ago. Same with every tesla model. Every year the cars are significantly different than previous models. The state of the market development is happening faster than the average consumer can keep up with.
