Why is this Secret Santa Stupidity being implemented in companies in Bangalore?

I have failed to understand this concept of Secret Santa, Why should I spend my time & energy to find a gift for someone in my company whom I barely know? . Last Year I put a lot of thought to buy a meaningful gift to a person whom I had not even heard of!. I received a 'Pen' that not only looked dirt cheap. It dint even work when I tried to write!. I clearly told the Company HR that "I won't be available for the reveal so I would like to opt out this time". It's also not good for the environment due to the unwanted purchase of junk!.. Last year some guy had wrapped slipper & gifted it!. It was very awkward. Some people are taking one's dp in watsapp & getting it printed & framed to gift 🎁. It l be helpful to their family to put a garland in case they die!. so thoughtful 😒🙄.. Some Haloween, this stupid secret santa,. valentine's day .etc have no relevance. Our country is filled with rich culture & heritage. we don't need these meaningless customs like secret santa .
