Sites generally designed around comsuption of information (e.g. news sites) do very frequently have limits on line lengths. While Wikipedia and Reddit are examples against this, a huge proportion of their visitors would be on mobile devices (who wouldn't have this issue) - though more or less than Wikia, I couldn't say.

It's certainly not an area with clear-cut answers - it's absolutely fair to have an opinion - but we do strongly believe this approach will be an improvement for the majority in the long-term.
