This article is 100% spot on though--it is a completely regressive policy and privileges those with enough capital to purchase real estate at the expense of those who have no choice but to rent.
As implemented, much of the benefit goes to the wealthy with both pricey primary homes and with secondary homes.
If you instead limited it to primary homes only and only up to, say, property prices 1.5 times the median single family home price for the area, you'd recover a majority of that deduction right off the bat without harming lower- or middle-income home ownership or causing a dive in property prices or lose the stability benefits of home ownership.
The deduction related to the purchase decision you just made will be a lot smaller by then and you would know what the new rules were for future decisions.
