Encore un article sur le sujet du plain text, qui explique très bien pourquoi on choisit rarement la solution la plus simple

It is a well-known engineering principle, that you should always use the weakest technology capable of solving your problem - the weakest technology is likely the cheapest, easiest > to maintain, extend or replace and there are no sane arguments for using anything else.

The main problem with this principle is marketing - few people would sell you a 10$ product that can solve your problem for ever, when they can sell you a 1000$ product, with 10$ per > month maintenance cost, that will become obsolete after 10 years. If you listen to the “experts” you would likely end up not with the simplest, but with the most advanced technology.

And with software the situation is particularly bad, because the simplest technologies often cost zero, and so they have zero marketing budget.
