To an extent this makes sense, like if there is a new company CEO who has a different vision, etc. But many of these decisions-- dropping Google Reader, the trend to ditch the headphone jack, and now Slack killing IRC-- seem to be made for no apparent logic reason, and giving some bullshit excuse like "security reasons."
Is this driven by data? If so, why don't they release the data and show us? Alternatively, in a free market, the way to best compete is to offer more options to your customers, unless you've attained a semi-monopoly, or have some kind of trust agreement.
Is it that difficult to maintain these things? Apple and Google are among the richest companies in the world, and Slack just raised $250 million. Given that not only are all three features I'm discussing established and probably only need occasional maintenance, the headphone jack has been around for over 100 years. It's not like they need new science breakthroughts for it.
None of it makes any sense, unless the entire Bay Area has gone Dilbert.
