Simple: Bitcoin is the victim of its popularity
actually bitcoin is a victim of 2 things:
the politics which are preventing us from moving forward in scaling bitcoin
and the spam attacks that are increasing the backlog to unrealistic numbers.
I personally advise against choice #2 as a hard fork would be disastrous for the unity of the network. We've recently had a glimpse of what would happen in case of a hard fork when one of them happened between ETH and ETC. Since it's happened most big blocks supporters seem to have stopped supporting them too. I mean, it would be open warfare between BTC and its fork and I'm sure that as an investor you and your money don't want to be caught in such an apocalypse. Also, as blocks would get bigger, security concerns would arise.
hard forks are not something to fear. if they are done right it is actually good and bitcoin has already have at least one hard fork in the past.
and you are comparing bitcoin's hard fork with an altcoin hard fork that
was performed in a wrong way without consensus the developers of eth one day decided they need to hard fork eth and then did it without reaching consensus among all so they ended up with two chains.
if bitcoin or any other project follows that path they will end up with disasters too.
but it if a big "if"... and so far as i know the consensus with bitcoin is more than 95%
