Can を be use instead of が?


I've heard that を is sometimes used instead of が nowadays. Although it is
strictly incorrect it is becoming more common. Is this true ?

For example:

お茶を好きです

車を欲しいです




This article by 東山篤規 is exactly about this topic: [助詞「が」と「を」の置換性について
─文例と世代の比較─](http://www.ritsumei.ac.jp/acd/cg/lt/rb/599/599pdf/higasiya.pdf)
The following table illustrates を is preferred by younger generations in some
contexts. The dagger (†/‡) in the rightmost column indicates a statistically
significant difference between the two generations.

Roughly speaking, younger people tend to prefer を with できる, 欲しい, ～たい, ～(ら)れる
and so on, especially in relatively complex sentences. I personally feel
私は車を欲しいです is a little unnatural (私は車が欲しいです sounds much better), but 車を欲しい人を探す
and 車を欲しくなる映画 somehow sounds fine.

Although not included in this table, I think the same tendency is found also
with 好き, 嫌い, etc. Still, a simple sentence like お茶を好きです is considered wrong
regardless of the generation.
