You don't have to be concerned with them. But a reasonable person recognizes that humans living in a society that isn't a communist country where the government provides for all needs of its citizens will need to engage in acts of commerce that produce revenue in order to live. And a reasonable person of average to below average intelligence can take that information into account in determining that it makes logical sense for a company run by people who have economic needs will price their goods in a way that makes it possible for them to pay the costs of living in their society. And while that person may not like the fact that the product they've used for so long for a single purchase price that, amortized over the course of their use may come out to less than $5 per year, the consumer would understand and accept the fact that it is necessary, rational, and reasonable for the price to increase.
In such case, the reasonable and rational consumer would either accept the increase and pay it willingly, or would decline to pay the increase and stop using the product. But in either case, any average intelligence possessing rational person would be accepting of a modest and long overdue price increase, and would proceed without complaint. Just my feelings on the matter after seeing this type of conversation come up EVERY single time some company that people have freeloaded on for years finally decides to actually *gasp* make money doing the work they do every day.
