I don't really know what this comment is supposed to imply, using the name of a currency and not the symbol is fairly common when talking about international currencies, since not everyone knows symbols or they can be confusing aka Euros/Pounds.
For example, here is a headline from a .co.uk domain that uses the word and not the symbol for Euro
When I saw "Rs", given that I work in an academically-related field, I first interpreted it as relating to the R statistical language.
Then, during the parsing of the title, my second interpretation was that "Rs 199" was the model number of some sort.
The letters "Rs" do not, as someone from North America, mean a currency to me. IMHO, using a 'special' character like ₹ would help me interpret things better.
If you work with R wouldn't it just be R? I've never seen R Studio abbreviated to Rs. If anything I could see a programmer interpreting it as rust but the capitalized R would be weird.
Techcrunch uses WordPress, which definitely handles '₹' just fine in titles and URLs, especially since WordPress is by far the #1 CMS used in India[1].
