Why was apple the best company of 2019? ?

Because they track and censor people? Or because their net worth is currently around $1 trillion dollars.

Explanation: Apple was the best company of 2019 because its net worth is about $1 trillion. Apple has gone from $265.6 billion in 2018 to $1 trillion in 2019 and is the first company to cross the $1 trillion dollar mark in market capitalization. They have an extensive array of technological products and are highly skilled at manipulating people into buying their products due to a combination of their seductive advertising and the fact that they crash people's phones about 2 to 3 years after purchasing and sometimes sooner!  In addition to all of these fine accolades, they have a crispy and juicy name, but I don't know if that has anything to do with their success as Blackberry has an awesome name too and they are not in the same financial league as Apple.

Hope this helps!  :)
