This "question" seems to focus on "New World Translation of the Holy Scriptures", which is distributed by Jehovah's Witnesses. There are more than 130 million copies of this modern-language bible in print, in dozens of languages.

The entire text of NWT is freely available at the official website of Jehovah's Witnesses, and a personal printed copy can be requested at no charge:

Jehovah's Witnesses certainly like NWT, but they are happy to use any translation which an interested person may prefer, and in fact Jehovah's Witnesses themselves distribute other translations besides NWT. Jehovah's Witnesses attach no particular infallibility or inspiration to NWT.
Since the same manuscripts used by the NWT translators are still widely available for study, and since there are dozens of alternate translations for comparison, anyone who chooses to use NWT does so informedly.
It seems that the vast majority of the criticism against the New World Translation is actually as a proxy for blind hatred against Jehovah's Witnesses. The hatred must be "blind" since secular experts of biblical Hebrew and Greek have consistently refused to condemn any particular verse or phrase as an unacceptable translation. Instead, it is religionists with preconceived theologies who bigotedly insist upon particular wordings, since these are necessary to prop up the shakey tenets of their false worship.
(2 Timothy 4:3-5) For there will be a period of time when they will not put up with the healthful teaching, but, in accord with their own desires, they will accumulate teachers for themselves to have their ears tickled; and they will turn their ears away from the truth, whereas they will be turned aside to false stories. You, though, keep your senses in all things, suffer evil, do the work of an evangelizer, fully accomplish your ministry.
It seems signficant that the relatively small religion of Jehovah's Witnesses are the ones best known for their worldwide preaching work. Yet Jesus commanded that ALL who would call themselves "Christian" perform this public work:
(Matthew 28:19,20) Go therefore and make disciples of people of all the nations, baptizing them in the name of the Father and of the Son and of the holy spirit, teaching them to observe all the things I have commanded you. And, look! I am with you all the days until the conclusion of the system of things.
